Printed charts still matter in Bangkok

Screens invite scrolling. Paper forces a decision: where does the swing start, where does the consolidation end, and what would invalidate the idea. Our Bangkok classroom therefore begins with printed packs even when the afternoon moves to live feeds.

Visitors sometimes ask whether paper is nostalgic. It is pedagogical. Once your hand has committed a mark, peer critique has something concrete to challenge. That habit transfers back to whatever platform you use after class.
